CHARLES W. ROBISON, OF MCKEES ROCKS, PENNSYLVANIA.

WINDOW-SASH FASTENER.

Application filed December To all whom it may concern:

Be it known that I, CHARLES W. Roinsor, a citizen of the United States of America, residing at Mcliees Rocks, in the county of Allegheny and State of' Pennsylvania, have invented certain new and useful lmprovements in Window-Sash Fasteners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to window sash fasteners, and its object is to provide a device of this character of simple and inexpensive construction adapted to support and secure either the upper or lower sash of a window in any position to which it may be adjusted.

The invention comprises a recesssed bar or plate secured to one side o the upper sash of a window, in conibination with a fastening device of novel construction secured to the top rail of the lower sash.

A The construction oi the improvement will be fully described hereinafter in connection with the accompanying drawing which lorms a part of this specification, and its novel features will be defined in the appended claims.

In the drawing, Figure l is a fragmentary front elevation of a window frame showing a portion oi an upper and lower sash withmy improvement applied thereto, Fig. 2 is a front elevation of the recessed metallic plate or bar employed, Fig. 3 is a detached view in perspective ot the fastening device carried by the meeting rail of the lower sash, Fig. 4 is a transverse vertical section of the same', Fig. 5 is a longitudinal vertical section of the fastener, on an enlarged scale, Fig. (i is a view in perspective O a modified construction of locking bolt,

and Fig. 7 illustrates another modified form oi locking bolt.

The reference numeral l designates one side oi a window frame, 2 the upper sash of the window, and 3 the lower sash thereof. 'lo the side rail of the upper sash 2 is secured 2L metallic plate or bar 4 having parallel arms 5, at its ends extending at right angles to the body of the plate or bar and formed with openings G `for the reception of nails or screws for securing the plate or bar to the upper sash. The outer edge of the plate or bar 4 is formed with recesses 7 to provide projections 8 adapted to rest against the inn er edge of the side rail of the upper sash as shown in Fig. l.

The locking device of the fastener comprises a bolthousing 9 and a sliding bolt l0. The housing is preferably ormed from a single piece or strip of sheet metal, bent to form a horizontal base flange 11, two parallel vertical side walls 12 connected at their upper ends by a web 13, a horizontal flange 14 consisting oi two thicknesses of metal, and an upwardly extending tongue l5 projecting upward between the sides l2 and terminating in a lip or lug 16 of approximately one-third the width o the tongue. In connection with the housing constructed asthus described, I employ a sliding bolt Specification of Letters Patent.

preferably formed with a straight slot 17 to receive the lug I6 oi' the housing, and having its outer end bent at right angles to provide a finger-piece IS. In addition to the straight slot I7 the outer end oi' the bolt l0 is formed with an L-shaped slot I9 to provide a locking lug 20 adapted to engage over one oi' the projections S.

Instead of the bolt shown in Fig. 5, I may employ a bolt ol' the construction shown in Fig. 7 in which a bayonet slot 2l is formed in the lower edge of the bolt. This bolt may be inserted into the housing after the latter is bent into completed form the space between the lug I6 and the connecting web lS-bcing of sufficient width to permit of the insertion of the bolt to bring the vertical portion o the bayonet slot into register with the lug I6 when the bolt will drop to permit the lug 16 to pass into the horizontal portion of the slot as shown in Fig. 7. I preferred, however, the bolt may be formed with a straight elongated slot 22 as shown in Fig. G, in which event the bolt must be placed between the sides of the housing beiore the tongue l5 is bent to form. The base flanges 1I and I4 o the housing are formed with screw holes 23 to receive screws for securing the housing to the meeting rail oi the lower sash.

The utility and operation of the improvement will be readily understood. The position o the recessed plate or bar Al with relation to the side rail of the upper sash provides a series of sockets to receive thc inner end of the bolt, and it is obvious that by manipulating the bolt to project it into the space between the adjacent projections 8, either sash may be locked at any position to which it may be adjusted. In other words, the upper sash may be locked in lowered position or the lower sash in raised position, or both, as may be dosircd.

It will be apparent that by constructing the housing in the manner described from a single metallic strip the device may be manufactured at small expense.

By employing the preferred orm of bolt shown in Fig. 5, the bolt is iirst pushed tlnoughone ofthe spaces 7, after which the sash is raised or loweredslightly to bring one o the projections 8 opposite the horizontal portion of the slot I9, when by drawing the bolt forward its lug 20 will engage over the projection 8 to lock the bolt.

I would have it understood that the invention includes all such modifications and variations in the details of construction, as may be resorted to without departing from the terms and scope oi the claims.

What I claim and desire to secure by Letters Patent, is

1. The combination with the upper and lower saslies ot' a window, of a plate provided with means for securing'it to the upper sash, and notched along one edge to provide recesses, a housing formed of a. single piece of metal bent to form flanges and :in upwardly projecting tongue within said housing, said tongue having a projecting lug, anda hook shaped bolt slidably supported within said housing and having a slot to receive said lug.

2. In a sash-fastener, the combination with an upper and a lower sash, of a notched bar secured to a side rail of the upper sash, and means carried by the meeting rail of the lower sash for engagement with said notched bar to lock the sashes in adjustable position, said means comprisA ing a bolthousing secured to the meeting rail of the lower sash and formed from a sheet-metal blank bent to form base anges and terminating at one end in atongue located within the housing and provided with a lug, and a lock-bolt slidable in the housing having a slot to receive said `lugT and adapted for engagement with said notched' bar.

In a sash-fastener, the Combination with an upper and a lower sash of a window, of a bar secured to one of the side rails of the upper sash and provided along one edge with recesses forming-projections, a b0lt housing se! cured to the meeting rail of the lower sash, a locking bolt mounted for sliding movement in said housing, means for limiting the movement of said bolt within the housing, said bolt provided atits inner end with an L-shaped slot adapted when the bolt is projected into one of the recesses in said bar to receive one of the projections on said bar, as and for the purpose described.

4. In a sash-fastener, a bolt-housing formed 'from a sheet metal blank bent to provide base-flanges and a vertical housing-portion, one edge of said blank being extended upwardly within the housing-portion and terminating in a laterally-projecting tongue of less width than said upwardly-extended edge' of the blank, a locking-bolt slidable in the vertical housing-portion, and having a slot receiving said laterally-projecting tongue, and means carried by one of the sash rails to receive said bolt.

In testimony whereof I ax my signature in the presf ence of two witnesses.
